Portable podium and performance platform system

A portable podium designed for selective resting engagement on a ground surface adjacent to a performance area said podium being selectively positionable between a transport orientation and a performance orientation, said podium comprising:

• a platform member having a top surface and a bottom surface, said top surface being oriented generally perpendicular to said ground surface when said podium is positioned in the transport orientation and said top surface being oriented generally parallel to the ground surface when said podium is positioned in the performance orientation;
• a support frame adapted for operable resting engagement with said ground surface operably coupled to and oriented to extend downwardly from the bottom surface of the platform member when said podium is oriented in said performance orientation, whereby the platform member presents a generally horizontal surface elevated above said ground surface when the podium is in the performance orientation;
• and
• a transport assembly means operably coupled to said support frame, the transport assembly means including:
• two or more wheels;
• and
• means for mounting each of the wheels on an axis of rotation that is generally perpendicular to the platform top surface and positioned to allow at least an arcuate section of the wheels to extend beyond a peripheral edge of the support frame, whereby the wheels engage the ground surface when said podium is in the transport position and the wheels clear the ground surface when said podium is in the performance position.

A portable performance platform system designed for selective resting engagement on a ground surface adjacent to a performance area, said performance platform system being selectively positionable between a transport orientation and a performance orientation, said platform system comprising:

• a base riser unit having:
• two adjacent parallel platform floor surfaces wherein the first floor surface is at a first height and the second floor surface is at a second height;
• two or more side means fixedly connected approximately perpendicularly to the floor surfaces, the side means supporting the first floor surface at the first height and the second floor at the second height, the side means maintaining the floor surfaces in a horizontal orientation with respect to the ground surface;
• and
• a transport assembly means operably coupled to at least one of the side means, the transport assembly means including:
• two or more wheels;
• and
• means for mounting each of the wheels on an axis of rotation that is generally perpendicular to the floor surfaces and positioned to allow at least an arcuate section of the wheels to extend beyond a peripheral edge of the floor surface, whereby the wheels engage the ground surface when said platform is in the transport position and the wheels clear the ground surface when said platform is in the performance position;
• one or more generally rectangular step members, each step member having a pair of opposing platform surfaces and two or more side supports;
• and
• hinge means operably connected to the base riser and each step member for pivotally connecting the step members to the base riser to allow the floor surfaces of the base riser and the planar platform surfaces of the one or more step members to be selectively configured into one of a predetermined set of platform riser configurations.
